Description

TECHNICAL FIELD This invention relates to a technique for assembling a wire harness to a vehicle.

A wire harness for electrically connecting electrical components on a vehicle has a shape that stretches around a narrow gap in the vehicle. Therefore, when the wire harness WH is unfolded, it spreads over a large area as a whole.

If such a wire harness is transported in an unfolded form, transport efficiency will be poor. Therefore, in order to improve the transport efficiency, after the wire harness is manufactured, the wire bundle is folded and bound with a temporary fixing tape that can be easily cut by hand to form a packing form.

Therefore, as the work of attaching the wire harness to the vehicle, the wire harness in the shape of a package is unrolled and laid on the vehicle, the projection of the engaging part is inserted into the hole on the vehicle side and fixed, and the connector of the wire harness terminal is fixed. is fitted to the electrical equipment on the vehicle side for electrical connection. In this case, among the component parts of the wire harness, the engaging part and the connector are handled.

Here, Patent Literature 1 discloses a technique of providing an information holding unit that holds information on the mounting position of each connector and the mounting position of each fixed part in a wire harness molded into a packing shape. Examples of the attachment position information for each connector include identification information unique to each manufactured wire harness, information managed by the model number of the wire harness, and the like.

Assuming that such a wire harness is attached to a vehicle by a robot, the robot may grasp the connector whose location is specified and connect it to the mating connector in the vehicle.

However, depending on the form of the wire harness, the connector to be handled by the robot may be connected to another component such as another connector. In such cases, it is difficult for the robot to handle multiple parts at the same time. Therefore, when the robot grabs one connector and moves it toward the mating connector, the other part also moves along with the movement of the one connector.

Then, when one connector is grasped and moved toward the mating connector, other parts may interfere with other parts of the vehicle. In particular, in a vehicle, various parts are densely packed, and wire harness installation work is often carried out in a very narrow environment, so other parts of the wire harness interfere with other parts of the vehicle.

A wire harness information management system according to an embodiment will be described below. FIG. 1 is a schematic overall view showing a wire harness information management system, FIG. 2 is a schematic view showing a wire harness module 10 in a packing form, and FIG. 3 is a schematic view showing a wire harness module 10 in a developed form. .

The wire harness information management system includes a wire harness module 10 including a wire harness WH, and a storage section 52 as an information storage section.

A wire harness module 10 includes a wire harness WH and a tag 12 .

The wire harness WH includes a wire harness body 14 and a plurality of vehicle assembly parts 16 and 18 provided on the wire harness body 14 . The wire harness WH is formed in a packing form.

The wire harness main body 14 is configured by bundling a plurality of electric wires 13 according to an assembly form in the vehicle. Here, a plurality of electric wires 13 are appropriately branched and bundled according to the wiring route of the vehicle. Binding is performed with a binding member such as an adhesive tape or a binding band. In addition, the wire harness main body 14 may be attached with an exterior member such as a corrugated tube or a protector. It should be noted that in each figure, the electric wire 13 is indicated by a single line regardless of whether the electric wire 13 is one or plural.

The vehicle attachment parts 16 and 18 are parts provided on the wire harness body 14 and attached to the vehicle. Here, the vehicle attachment parts 16 and 18 include the connector 16 and the vehicle fixing part 18 . Hereinafter, the vehicle attachment parts 16 and 18 may be distinguished and described as a connector 16 and a vehicle fixing part 18 .

The connector 16 is attached to the end of the wire harness body 14 and connected to a mating connector. The mating connector is, for example, a connector for various electric parts mounted on a vehicle. The connector 16 is assembled to the vehicle by inserting and connecting the connector 16 to the mating connector. Thereby, the end of the wire harness main body 14 is supported at a predetermined position of the vehicle.

As the vehicle fixing part 18, a clamp part with a band, a clamp part with a sleeve, or the like is assumed. The banded clamp component is fixed to the wire harness body 14 by winding the band portion around the wire harness body 14 . The sleeved clamp component is fixed to the wire harness body 14 by winding and fixing the sleeve portion to the wire harness body 14 with an adhesive tape or the like. The vehicle fixing component 18 is fixed to the vehicle by inserting and fixing the vehicle fixing component 18 into a fixing hole formed in the vehicle body. By fixing the vehicle fixing component 18 to a predetermined position of the vehicle in this manner, the intermediate portion in the extending direction of the wire harness body 14 and the like are supported at a predetermined position along a predetermined wiring route.

An identification code is assigned to the wire harness WH. This identification code is recorded on the tag 12 . The identification code may be a number unique to the manufactured wire harness WH or may be a number for each lot of the manufactured wire harness WH. Here, it is assumed that the identification code is a unique identification code for each wire harness WH. The identification code may be recorded on the tag 12 in an electromagnetically or optically readable format. For example, a graphic symbol such as a bar code may be printed on the tag 12 so as to be optically readable. The tag 12 may be provided with a magnetically readable magnetic stripe. The tag 12 may include a wireless tag device that wirelessly transmits the stored identification code using electromagnetic fields or radio waves. The tag 12 may be printed with human readable letters or numbers.

The tag 12 is attached to the wire harness WH by partially winding it around the wire harness WH, sticking it to the wire harness WH, or via a linear body such as a wire.

The wire harness WH is manufactured by spreading a plurality of electric wires on a wire harness assembly drawing board and binding them at appropriate locations. The manufactured wire harness WH has, for example, a form in which at least one (here, four) branch wire portions WHb are branched from a main wire portion WHa (see FIG. 3). The manufactured wire harness WH is laid out on an inspection drawing board, and the wire harness WH is subjected to an inspection such as continuity test on the inspection drawing board. After the inspection, the wire harness WH is removed from the inspection drawing board and formed into a packing form.

When forming a packing form, the wire harness WH is made compact and outwardly by folding the trunk portion WHa of the wire harness WH in a U shape or by folding the branch wire portion WHb onto the trunk portion WHa. A form with few protruding parts is used (see arrows in FIG. 3). In this state, the trunk line portion WHa and the branch line portion WHb that have been folded are kept in a state of being bound by a binding member 11 for forming a packing shape (see FIG. 2). As the binding member 11 for forming the packing shape, for example, an adhesive tape having cuts can be used. By forming the wire harness WH in the packing form in this way, the transportation efficiency of the wire harness WH can be improved.

The tag 12 is attached to the wire harness WH at the time of manufacturing and inspecting the wire harness WH, at the time of forming the wire harness WH into a packing form, or at a later timing.

The storage unit 52 is the storage unit 52 of the management server 50 . The storage unit 52 stores position information 53 regarding at least one of the plurality of vehicle assembly parts 16 and 18 in the packing form of the wire harness WH, and shape information 54 of the wire harness WH in the unpacked state. are doing. Here, the storage unit 52 stores position information 53 and shape information 54 in association with the identification information.

That is, the management server 50 is configured by a computer including a processor and a storage unit 52 . The management server 50 may be composed of a single computer, or may be composed of a plurality of computers.

The storage unit 52 stores position information 53 and shape information 54 in association with the identification information.

The identification information is identification information assigned to the wire harness WH and recorded in the tag 12 .

The position information 53 is information indicating the positions of the connector 16 and the vehicle fixing part 18 in the packing form. The position information 53 is, for example, position coordinates of the connector 16 and the vehicle fixing component 18 in a three-dimensional coordinate system. This position information 53 is provided as position information when a robot that assembles the wire harness WH to the vehicle grips the connector 16 and the vehicle fixing part 18 . The position information 53 may be generated by an operator or the like inputting the positions of the connector 16 and the vehicle fixing part 18 in the wire harness WH in an ideal packing form. In this case, as will be described later, when the robot grips the connector 16 and the vehicle-fixed part 18, the area where the connector 16 and the vehicle-fixed part 18 are expected to exist is imaged, and based on the image data, the connector 16 and the vehicle are detected. Object recognition of the stationary components 18 may be performed to determine their more precise location.

In this case, even if the connectors 16A and 16B and the vehicle fixing part 18 to be gripped are hidden by the wire bundle or the like, the positions can be specified, so that the gripping operation can be performed smoothly.

The position information 53 is generated by performing object recognition of the connector 16 and the vehicle fixing part 18 from two-dimensional data or three-dimensional data obtained by imaging the wire harness WH in the form of packing with a two-dimensional camera or a stereo camera. may

As will be described later, when the robot grips one connector 16, other connectors 16 close to it may move according to the one connector 16 concerned. It is not necessary to specify the positions of the other connectors 16 in the packaging form. Therefore, the positional information does not need to include all positional information of the connector 16 and the vehicle fixing part 18 in the form of packaging.

The shape information 54 is shape information of the wire harness WH in an unpacked state. Such shape information is obtained when the robot that assembles the wire harness WH to the vehicle grips one of the connectors 16 and the vehicle fixing parts 18 (for example, one connector 16) and directs it toward the fixing destination (for example, the connection destination connector). It is provided as data for estimating the movement, position, etc. of the other connectors 16, the vehicle fixing parts 18, etc. that move with the movement of the one connector 16 when moving. After fixing one of the connector 16 and the vehicle fixing part 18 (for example, one connector 16) to the fixing destination (for example, the connection destination connector), the shape information indicates the position of the other connector 16, the vehicle fixing part 18, and the like. It can also be provided as data for predicting etc.

Here, the shape information 54 includes design information 54a and specific information 54b.

The design information 54a is information on the design of the wire harness WH. For example, information such as from which position in the main line WHa the branch line portion WHb branches, the length of the branch line portion WHb, the distance from the branch portion to each connector 16, the distance between the connector 16 and the vehicle fixing part 18, and the like. is.

The design information 54a is common information for wire harnesses WH having the same product number.

The unique information 54b is unique information of the wire harness WH that is actually manufactured, and is unique information that differs for each wire harness WH that is actually manufactured even if the wire harness WH has the same product number.

That is, since the wire harness WH is formed by binding a plurality of flexible electric wires with a flexible adhesive tape or the like, the extension direction of the branch wire portion WHb, the bending of the trunk wire portion WHa and the branch wire portion WHb There may be individual differences in terms of direction, etc.

For example, as shown in FIG. 4, even if the branch line portion WHb is designed to extend at a predetermined angle with respect to the trunk line portion WHa, there may be subtle differences depending on how the adhesive tape is wound. can occur. Therefore, the branch line portion WHb can extend at an angle larger or smaller than a predetermined angle with respect to the main line portion (see the branch line portion WHb indicated by the two-dot chain line).

Further, for example, as shown in FIG. 5, the main line portion WHa or the branch line portion WHb is subtly bent and peculiar depending on how the adhesive tape is wound around the bundled electric wires or the peculiarities of the electric wires. (Refer to the branch line portion WHb indicated by the two-dot chain line).

The specific information may be image data of the wire harness WH, for example. The imaging data may be two-dimensional data or three-dimensional data. By recognizing the shapes of the trunk line portion WHa and the branch line portion WHb from the imaging data and tracing their paths, the extending direction of the branch line portion WHb, the degree of curvature of the trunk line portion WHa and the branch line portion WHb, and the like are recognized. be able to. The unique information may be the imaging data itself, or may be data indicating the extending direction and the degree of bending obtained from the imaging data.

The information specific to the wire harness WH is likely to appear remarkably in a form in which the wire harness WH is not formed in a packing form, that is, in a non-restrained form. For this reason, it is preferable that the imaged data is imaged data after the wire harness WH is manufactured and before it is formed into a package. Specifically, after removing the manufactured wire harness WH from the wire harness assembly drawing board and before setting the wire harness WH on the inspection drawing board, after removing the wire harness WH from the inspection drawing board Image data obtained by imaging the wire harness WH in any state before the wire harness WH is formed into the packing form may be used. The imaging data is transmitted from the imaging device to the management server 50 together with the identification code of the wire harness WH that is the imaging target, and is stored in the storage unit 52 in association with the identification code.

However, the imaging data may be obtained by imaging the wire harness in the form of packing.

The management server 50 is communicably connected to the terminal device 20 through the communication line 40 .

The terminal device 20 is provided in a factory or the like where the wire harness WH is assembled to the vehicle. When the wire harness WH in the form of packaging is brought into the factory, the identification code assigned to the tag 12 of the wire harness WH is input to the terminal device 20 . The identification code may be input through a reader capable of reading the identification code of the tag 12, or may be input by an operator.

When the identification code is input to the terminal device 20 , the identification code is transmitted to the management server 50 . Upon receiving the identification code, the management server 50 reads the position information 53 and the shape information 54 corresponding to the identification code from the storage unit 52 and transmits them to the terminal device 20 .

The terminal device 20 transmits the position information 53 and the shape information 54 to the vehicle mounting device 30 for assembling the wire harness WH to the vehicle. The vehicle mounting device includes a robot such as an articulated robot and a control device for controlling the robot, and controls the robot while referring to the position information 53 and the shape information 54 to connect the connector 16 and the wire harness WH of the wire harness WH. The work of assembling the vehicle fixing component 18 to the vehicle is carried out.

An assembly work example using the position information 53 and the shape information 54 will be described.

As shown in FIG. 6, two electrical devices 62 and 64 are arranged behind the reinforcement 60, and two connectors 16 are inserted into the electrical devices 62 and 64 from the front side. Here, in order to distinguish between the two connectors 16, the connector 16B at the end of the main line portion WHa and the connector 16A at the end of the branch line portion WHb branching from the main line portion WHa are used. An L-shaped bracket 66 is arranged on the way of the connector 16A toward the electric device 62 . It is assumed that the bracket 66 is positioned below and on one side of the main wire portion WHa connected to the connector 14A via the branch wire portion WHb.

In this way, when the connectors 16A and 16B of the wire harness WH are inserted and connected to the electric devices 62 and 64, there are cases where various parts of the vehicle are present on the way. In such a case, if the connectors 16A and 16B interfere with the bracket 66 or the like, the connectors 16A and 16B may get caught on the bracket 66 or the like, hindering smooth operation or causing damage to the connectors 16A and 16B. Therefore, consideration should be given to suppressing such interference.

For example, consider a case where an operator manually inserts and connects the connectors 16A and 16B to the electrical devices 62 and 64 and fixes the vehicle fixing component 18 to the bracket 66 . In this case, for example, with the connector 16B held in the left hand, the connector 16A is pinched with the fingertips of the left hand and inserted into the electrical device 62, then the right hand is turned from the right side of the bracket 66 to connect the connector from the left hand to the right hand. 16B is changed and the connector 16B is inserted into the electric device 64 for connection. After that, a procedure of holding the vehicle fixing component 18 with the right hand and fixing the vehicle fixing component 18 to the bracket 66 so that the excess length of the harness is appropriate is assumed.

Similarly, when the work is performed by a robot, it is assumed that the work is performed in the order of inserting and connecting the connector 16A, inserting and connecting the connector 16B, and fixing the vehicle fixing part 18. As shown in FIG. In this case, a dual-arm robot or the like equipped with a hand capable of gripping a plurality of parts may be able to perform work similar to that of a human.

However, it is difficult to realize a hand that simultaneously handles a plurality of connectors 16A, 16B and vehicle fixing parts 18 that are in a positional relationship apart from them. Also, since the harness assembly work tends to be concentrated in one part of a large area, it is relatively difficult to plan the work suitable for an expensive dual-arm robot with a large work area. For this reason, it is preferable to assume that one articulated robot or the like that handles each part is used for the work.

In that case, as shown in FIG. 7, the connector 16A is removed by breaking the binding member 11 from the wire harness WH partially or wholly kept in the packing form, and then, as shown in FIG. Alternatively, the connector 16A may be linearly moved toward the electric device 62 for insertion and connection. However, in this case, the branch wire portion WHb extending from the connector 16A is connected to the middle of the trunk portion WHa and folded, and the connector 16B is attached to the end of the trunk portion WHa on the tip side from there. If the connector 16B is also dragged along with the linear movement of the connector 16A, the connector 16B and the trunk portion WHa connected to the connector 16B may interfere with the bracket 66 and the like.

Therefore, if the shape information 54 is provided in advance to the controller of the robot, it is possible to estimate the movement and position of the connector 16B and the main line portion WHa connected thereto when the connector 16A is inserted into the electric device 62. . For example, based on the shape information such as the length of the branch line portion WHb extending from the connector 16A, the length of the portion of the main line portion WHa from the portion where the branch line portion WHb is connected to the connector 16B, movement of the connector 16A is performed. It is possible to predict how far away from the route the connector 16B and the trunk portion WHa may exist. Based on this prediction, it is possible to create an operation path plan for suppressing interference between the connector 16B, the trunk portion WHa, and vehicle parts.

For example, when it is predicted that the portion of the connector 16B and the trunk portion WHa on the connector 16B side can exist within a distance range of x cm from the movement path of the connector 16A, as shown in FIG. The movement path P should be set so that the path P passes through a distance of x cm or more from the position of the bracket 66 . At this time, considering the length of the portion of the main line portion WHa from which the branch line portion WHb is connected to the connector 16B, the moving route P is set so as to pass through a distance larger than x cm. may

It is assumed that the positional information of the vehicle parts such as the bracket 66 is stored in the control device itself of the robot that performs the assembly work.

As the shape information 54, the design information 54a can be used as described above.

Further, as described above, individual differences may occur in the shape of the wire harness WH made of a flexible material. Therefore, if the unique information 54b is included as the shape information, it is possible to execute the motion path planning according to the individual difference in the shape of the wire harness WH based on the unique information 54b. For example, if the branching direction of the branch line portion WHb from the main line portion WHa is close to the vertical direction with respect to the main line portion WHa, the movement path of the connector 16A should be set to be farther away from the vehicle parts in order to suppress interference. Just do it. Also, if the branch line portion WHb branching from the main line portion WHa is inclined at a small angle with respect to the main line portion WHa, the movement path of the connector 16A is set so as to pass closer to the vehicle component. good too. Further, when the movement and position of the connector 16B and the like estimated from the branching direction are positions that interfere with vehicle parts, the moving route P may be changed so as to avoid the interference. Also, the posture of the connector 16A gripped by the robot may be changed to change the movement and position of the connector 16B and the like.

After setting the movement path P based on the design information 54a, the robot controller may correct the movement path P based on the unique information 54b, or set the movement path P based on the unique information 54b. In the latter case, the design information 54a may be omitted.

Similarly, if the main line portion WHa and the branch line portion WHb have a tendency to bend, the movements of the connector 16B and the trunk portion WHa during the movement of the connector 16A are predicted in consideration of the bending habit. , based on this prediction, an operation path plan for suppressing interference between the connector 16B, the branch line portion WHb, and vehicle parts may be created.

Also, as shown in FIG. 10, after the connector 16A is connected to the electric device 62, the connector 16B may be positioned behind the bracket 66, etc. It is assumed that it will be difficult to recognize the connector 16B.

Even in such a case, since the position of the connector 16A connected to the electric device 62 is determined, the robot control device determines the position of the connector 16B based on the shape information with reference to the position of the connector 16A. position can be inferred. For this reason, the control device of the robot moves the camera for object recognition on the robot side to a position for capturing an image of the predicted presence area of the connector 16B, thereby capturing an image of the connector 16B. can be recognized.

In this case, similar to the above, the shape information 54 may be the design information 54a. Also, if the shape information 54 includes the unique information 54b, the position of the connector 16B can be predicted more accurately.

As a result, even when it is difficult to secure a sufficient field of view for recognizing the vehicle assembly parts 16 and 18, the vehicle assembly parts 16 and 18 can be recognized and gripped. It can be implemented efficiently.

Then, when the connector 16B is grasped by the robot and inserted into the electric device 64 and connected to the electrical equipment 64, and the vehicle fixing part 18 is fixed to the bracket 66, the connectors 16A and 16B of the wire harness WH and the vehicle fixing part 18 are connected as shown in FIG. is attached to a predetermined position of the vehicle.

According to the wire harness information management system configured as described above, based on the position information 53 stored in the storage unit 52, at least one of the vehicle assembly parts 16 and 18 in the packing form of the wire harness WH is selected. Can identify location. This facilitates, for example, the operation of gripping the vehicle assembly parts 16 and 18 by a robot. Further, when assembling at least one of the plurality of vehicle assembly parts 16, 18 to the vehicle, the other vehicle assembly parts 16, 18, 16, 18 are determined based on the shape information 54 of the wire harness WH in the unpacked state. 18 movements, positions, etc. can be predicted. Therefore, the wire harness WH can be assembled to the vehicle while suppressing the interference of the vehicle assembly parts 16 and 18, which are components of the wire harness WH, with the parts of the vehicle. Suitable for

Further, since the shape information 54 includes specific information of the actually manufactured wire harness WH, when at least one of the plurality of vehicle attachment parts 16 and 18 is attached to the vehicle, the wire harness WH is Based on the inherent information, movement, position, etc. of other vehicle components 16, 18 can be predicted. Therefore, the wire harness WH can be assembled to the vehicle while preventing the vehicle assembly parts 16 and 18, which are components of the wire harness WH, from interfering with parts of the vehicle.

The unique information can be easily obtained by including the imaging data of the wire harness WH as the unique information.

In addition, if the imaged data is imaged data after the wire harness WH is manufactured and before it is formed into a packing form, it can be data in which the peculiar peculiarities of the wire harness WH and the like remarkably appear.

Moreover, since the memory|storage part 52 is the memory|storage part 52 of the management server 50, it suffices to register an identification code to the tag etc. at the wire harness WH. This facilitates information management.

{Modification}
In the above embodiment, an example in which the position information 53 and the shape information 54 are stored in the storage unit 52 of the management server 50 has been described, but in the wire harness module shown in FIG. A device may be used and the tag 12 may store the position information 53 and the shape information 54 .

In this case, by attaching the tag 12 to the wire harness WH, the position information 53 and the shape information 54 can be associated with the wire harness WH. It can be used for control and the like.

The form in which the position information 53 and the shape information 54 are stored in the tag 12 is an example of a wire harness module in which the position information 53 and the shape information 54 are stored in the information storage unit handled together with the wire harness WH.

As the information storage section, various electromagnetically or optically readable recording media can be used in addition to a semiconductor memory.

As a form in which the information storage section storing the position information 53 and the shape information 54 is handled together with the wire harness WH, the information storage section is stored together with the wire harness WH in a storage container or the like.
